WILLIAM B. MOORE, OF CHICAGO, ILLINOIS;

GAS GENERATOR.

Application filed July 21,

To all whom it may concern Be it known that I, WILLIAM B. Moons, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Gas Generator, of which the following, when taken m connection with the drawings accompanying and forming a part hereof, is a full and complete description.

This invention relates to gas generators which are principally used to obtaln gas suitable to maintain oXy-hydrogen flames.

Among'the objects of this invention are to obtain a gas generating apparatus which is durable, eiiicient in operation; which is readily understood and easily operated, and

. Fig. 1.

is economically operable.

In the drawings referred to Fig. 1 is a vertical sectional view ofa gas generator embodying this invention, showing an oxy-hydrogen burner in elevation connected thereto, and

Figs. 2 and 3 are horlzontal sections, on lines 22 and 33, of Fig. 1, respectively, viewed in the direction indicated by the arrows. k

A referencecharacter applied to deslgnate a given part indicates said part throughout the several figures of the drawlng, wherever the same appears.

A represents a vessel or container. represents a chamber in said container, which is open at the top thereof, and adapted hold water, and C an additional chamber, 1n said vessel, hereinafter termedthe dehydrating chamber. Chamber C is separated from chamber B by horizontal partition 6, sa d partition being termed a false bottom to said chamber B. D represents a container having a lower and an upper chamber, (d, al which are separated by the forammated partition E; the smaller apertures 111 said partition being designated bythe characters 0, e, and a large aperture in said partition by the character F. The aperture F is provided on the sides thereof with the upwardly ex tending lips or ribs 7", f. Gr represents a pipe or tube which is open at one end and pro vided near the lower end thereof, (in chamber (Z with the aperture 9, communicating with said chamber. The lower end of. this tube or pipe G is closed as by plug 9 (See Said. lower end issecuredin partition H, H, (Fig.2) represent abutments to the walls of vessel A, adjacent to the upper Specification of Letters Patent.

end of said walls. I represents a cross member which may be positioned on, or under said abutments H, H. W hen the apparatus is inoperation, as will be hereinafter described, sald cross member I is positioned under abutments H, H, as is illustrated in Figs. 1

and 2. J represents a U-shaped member which is loosely mounted on cross member I, and K represents a screw threaded thumb screw which fits in screw threaded aperture corresponding therewith inmember J. Cross member I and the U-shaped member J are respectively provided with apertures which are slldably fitted on pipe or tube G, and when thumb screw K is turned firmly agalnst the side of cross member I, as is illustrated in Figs. 1 and 2 of the drawings, sald members Iand J are rigidly held thereby 111 an adjusted position on said pipe or tube. once, by means of said members I, J, and K, thecontainer D is adjustably placed and held in any desired position below the surface of the water, (represented by character X, in Fig. 1,) in chamber, B, when the apparatusis in operation, as by gas generated in chamber (l said container l) and pipe or tube G are forced upward, to

bring the ends of cross member I against abutments H, H. Lrepresents a flexible tube which connects the upper end of pipe or tube G with the upper end oft'ube or pipe M. The lower end of said tube or plpe M 1s open and communicates with dehydrating chamber O. Pipe or tube M is contained in chamber B, projecting a short distance into said dehydrating chamber, eX-

tending through thepartitionb, and being made water tight between it and said partition. N, O, 0 respectively represent pipes or tubes which communicate at the lower cock p being open) with the saturator S, throu h the flexible pipe P. The pipe or tube ispositioned outside of the vessel A,

and the upperend thereof is in communication, (stop cock 39 being open) with oxy-hydro burner Q, through flexible pipe 9 The pipe or tube 1 is also positioned outside the vessel A, and the upper end thereof is in communication with pipe or tube 0. R represents a stick of lime, which is made incandescent by the flame directed thereunto from hand wheel R is slidably mounted on horizontal part Q of the burner, and is rigidly connected to nozzle 9 of burner Q. S represents a carbureter, known in the art as a saturator. It is loosely filled with cotton, and when about to be used is charged with liquid ether, and the flow of gas therethrough vaporizes said ether, the gas thereby becoming saturated therewith. By said vaporization the vaporized gas becomes cooled from the. temperature at which the gas enters the saturator.

The discharge side of the 'saturator S is in communication with burner Q, (stop cook 19 being open), by flexible pipe P 7* repre-' sents a base which is positioned to one side of the horizontal part Q of burner Q, and is secured to and supported by member 1, mounted on said horizontal part. r represents afiexible shaft, which extends through base 1", being provided with screw threads fitting correspondingscrew threads in said base, and with the hand wheel-R- at one end thereof. Vertical adjustment of lime stick R. relative to the nozzle 9 is obtained by turning the flexible shaft 1, by means of t represents a tube which member 1, (on one side of said base-r), and to the member having thumb screw T therein.; Lime stick R is adjusted horizontally relative to nozzle 9 by sliding members?" and tjon the horizontal partQ of the burner and is secured in said adjusted position by.

the thumb screw T. U represents a base and a a standard to said base, u jrepresents a member which is slidable on standard a, and a a thumb screw by means of which mem her al is maintained in itsgadjusted position on said standard.

7 from chamber B and xdne inserted in chamber al dead container, through aperture F, and said membersreplaced in chainber 13, said chamber is'nearly filled with water (X), and said water flows under the bottom edge of said container into chamber (Z andv through the apertures in partition'E,

into chamber d there-coming intoicontact .withsaid oxone. Gases generated and-said gas forces water, l(by=1ts expansion and pressure), out of 'said chambers Z, al and thereby, container Duand' its contents are of less aspecific gravity than .said water, and said container forces pipe LG. and. cross .mem-" her. I, ..(;secured an adjusted position towards. the top.

thereon as hereinbetore described), upward, and said cross member being turned, (togeth'erwith container D and pipe G), to

bring the ends of said cross member underneath abutments H, H, said container is maintained in position below the surfaceof the water X, (determined by the adjustment of cross member I on pipe G). Gas generated as last above described flows into pipe G, through the open end of said pipe from chamber cl and through aperture 9 from chamber d and from thence flows through pipe G, flexible pipe L and pipe M 'intothe chamber G. In the generating of gas as last above described considerable heat is developed and the water X is heated, the upper portion or part of said water becoming hotter than the lower portion or part thereof, and by conduction, the false bottom 6 is heated, but to a less de me than the upper-portion of water X. f he contents of chamber C are thereby maintained in a warmed condition, but of less temperature than the upper portion of water X, and the extent of vapor saturation of the contents .of chamber C will be less than in pipes G, L and M; but greater than in pipes() and 0 Some of the contents of chamber 0, determined by stop cocks p flow through pipes N, P, to

the' saturator S, and from thence through p pe P to burner Q,"becoming saturated with vapor 1n its passage through the saturator S. The temperature of the gas flowingthrough pipe N'to saturator' S is illcreased from the temperature thereof in chamber C by the increase in temperature in water Xat the upper portion thereof,

while. the temperature of the gasfiowing through pipe 0 is lowered, it not passing through said water, but being outsidethereof, and being further cooled in its flow through said pipe 0, (or 0 The desired difference in temperature in gas delivered to thesaturator and directly to the burner is thus secured.

Variation of pressure to the gas generated is obtained by the variation of the position of bar I on pipe Gr. Dehydration of the gas flowing through the pipe O, (or

0 is obtainedby means ofsaidgas cooling during said flow, and the watercf condensation obtained flows back into chamber 0;

hence the gas delivered from said pipe 0 to the burner is. dry and icomparatively cool.

2 While'the water in chamber Bis heated inthelower part thereof, (coming against the false bottom 6), it is foundin practice that the temperature of the water is the greatest at the top or surface thereof, the heat gradually .increasingfrom the bottom It is well lmown that evaporation of a 'hquidjreducesthe temperature of the eontainerfthereof; and in practice it is found that by introducing heated gas to a saturator "continuous evaporation can be effected therein without reducing the temperature of said saturator and of the contents thereof below an operable temperature, and by conducting gas from the dehydrating chamber C, upwards in pipe N, throu h the highly heated water in chamber and deliverin said gas to the saturator as illustrated and described a hot gas, which is well dehydrated, is delivered to said saturator.

The delivery of a dry gas to the saturator and to the burner, one of said gases being cooled and the other at a high temperature, is thus effected; the said dryness of the cooled air being assured by the pipe or tube 0 which in case any water from chamber C enters pipe or tube 0, equalizes the pressure above said water with the pressure in said chamber, and thereupon said water in said pipe flows, by gravity, out of said pipe and into said chamber.
